Figure 3. Comparison of diagnostic accuracies of the blood 88-miRNA signature and serum AFP for HCCs and non-HCC subjects in discovery and validation sets. (A) The diagnostic accuracies of the blood 88-miRNA signature and serum AFP was compared by Receiver operating characteristic (ROC) analysis in the discovery set. (B) The diagnostic accuracies of the blood 88-miRNA signature and serum AFP by ROC analysis in the validation set.
